Right, I did this and run 'ldconfig' afterward but  its
/etc/ld.so.conf.d/nosegneg.conf not /etc/ld.conf.so.d/nosegneg.conf , may be
typo

Once you've done that, you can verify the linker knows about Xen variant

I get this before echo thing...

ldconfig -v -p 2>&1 | grep libc.so
        libc.so.6 (libc6, OS ABI: Linux 2.6.9) => /lib/libc.so.6


Once I create the hwcap setting & re-run ldconfig it shows

After hwcap I get ..

ldconfig -v -p 2>&1 | grep libc.so
        libc.so.6 (libc6, hwcap: 0x0018000000000000, OS ABI: Linux 2.6.9) =>
/lib/i686/nosegneg/libc.so.6
        libc.so.6 (libc6, OS ABI: Linux 2.6.9) => /lib/libc.so.6

But still getting those  '4gb seg fixup, process' errors

ldconfig is enough not need to reboot the guest right?

Thanks. Askar
